  outs, err := bson.Marshal(m)
   query := bson.M{}
    for k, v := range m {
      query = bson.M{k: v}
   }
  // var result []ReFeedback
   var result1 []ReFeedback

count, err := c.Find(outs).Count()
conf.CheckErr(err)
if size > 50 {
    size = 50
}
c.Find(outs).All(&result1)
     //c.Find(bson.M{"SecuCode": "000001"}).Skip(page * size).Limit(size).Sort("-timeDate").All(&result)

你好：

同样都是用的outs这个结果，count可以查出来，但是下面的result1 查不出来，不是很理解，请教下博主

Hi @xhochipe

Your ReFeedback struct must have the same names, or bson tags:

type ReFeedback struct {
    Field1 string `bson:"field_name_1"`
    Field2 string `bson:"field_name_2"`
}

Where field_name_1 is the name in mongo.

If this doesn't work, please post a runnable example - good luck!

dddd 那个文档集合和现在看到的mongo的数据集合是同一份数据，字段(field) 是相同的

Hi @xhochipe

It is very strange - do you have a test function I can run to reproduce? I tried something similar and it works OK for me.
